In case you weren’t aware – there’s a free download from Microsoft that allows you to change your interface to a snazzy dark grey theme.

You can download it at http://go.microsoft.com/fwlink/?LinkID=75078.

The screenshot I’ve included shows the theme after installation on my system. The background is not included with the theme, I found that one at http://wallpapers.jurko.net/pic/9005/. I’ve got a calculator window open as well as the start menu with a hilighted item and tooltip showing the general color scheme of things.
